Diatremic tuff-breccia deposits in Valle Giuffari, a bow-shaped valley cut in the southeastern slope of Monte Lauro (central part of the Hyblean Plateau), which represent the most important xenolith occurrence in the Hyblean Plateau. Deep-seated xenoliths entrained in the diatremic tuff-breccia consist of mantle peridotites (spinel-facies harzburgite and rare lherzolite), pyroxenites, gabbroic rocks including sheared oxide-gabbros, and sedimentary lithologies.
